WebIf meiosis happens many times, as it does in human ovaries and testes, crossovers will happen at many different points. This repetition produces a wide variety of recombinant … WebHeld together by a protein structure known as a synaptonemal complex, the chromosomes swap genes in a process known as crossing over. Crossing over increases the genetic variation of gametes and overall genetic diversity within a population. During metaphase I, homologous chromosomes are separated. Sister chromatids remain intact during meiosis I. Web8 aug. 2024 · The human body is made up of trillions of somatic cells with the capacity to divide into identical daughter cells facilitating organismal growth, repair, and response to the changing environment.
